IMPRQVEMENT IN GRAIN-BINDERS.

Specifcat'mz forfmngpart of Leftcrg `Patent No. 49,756, dated Scpfcmbcr 5, v1.865.

To all whom it may concern:

Beit known that we, JOHN F. HEMPERLY and CHARLES BARNS, of West Liberty, in the county of Muscatine and State of Iowa, have invented a new and Improved Device for Binding Grain and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specilication.

This invention relates to a new and improved device for bindin g grain, the same being designed to be applied to a harvest-er, and to be operated simultaneously therewith.

1n the accompanying drawings, Figure-1,

' Sheet No. 1, is a plan or top view of our invention; Fig. 2, a detached and enlarged plan or top view of the twisting and cutting device;

Fig. 3, a" detached view ot' a wire band.

twisted and cut .from the wire ou Jthe spool. Fig. 4, Sheet No. 2, is a side view of the 1invention artl in section- Fin'. 5 a ver- -of which has an upright, and a portion a hori zontal position.

D is an arm which projects at right angles from the upper horizontal part of the frame U, and has a toothed sector, E, secured to it by a pivot-bolt, a., said sector gearing into a pinion, F, the axis b ot' which is tubular, and has its bearings in the arm D. (See Figs. 5 and 7.)

On the top of the axis of the pinion F there is a. circular plate, G, which has a V-shaped notch, c, made in it, extending from its center to its periphery, as shown in Fig. 2.

' H H are two curved plates, between which a slotted slide, I, is fitted, said slide being also of curved form, corresponding with the plates H, and working in grooves d, made in the in ner surfaces of said plates. This slide I has a cord, J, attached to its rear end, said cord passing through a-hole in one of the plates H, and

connected to a lever, K, of a shaft, L, the bearings ot which are on the framing A. VThe toothed sectir E is also connected by a cord, M, to the lever K, as shown in Fig. 1.

N is a support attached to the arm D, and having ahorizontal shaft, O, in its upper end, on which a spool, l", is placed loosely, said spool having the wire A wound upon it i'rom which the bands are formed.

Adjoining the spool 1, and on the same shaft O, there is placed loosely a pulley, Q. This pulley and the spool are connected by ratchets c e, which are kept in contact by a spiral spring, f, on the shaft 0. (See Fig. 5.) The pulley Q has astrap, It, upon it, which is attached to the upper end ot'a lever, S,the lower end of the latter, below its fulcrum g, being connected by alink, 11.,.fwith an arm, i, onshait L.

By this arrangement it will be seen that when the lever l is moved in one direction the lever S will be moved simultaneously in an opposite direction.

T is a spring, one end of which is secured to the arm D, and the opposite end to an arm, U, which is secured by a pin orbolt, j, to the toothed sector E. This spring has atendency to throw the toothed sector in the direction indicated by arrow l.

Vis a spring-catch attached to the lower part of the support N, and designed for holding the toothed sector E in position at the termination of its movement in the direction of the arrow 2.

'W is an arm attached to a shaft, X, underneath vthe bed or platform B, and which is connected by geared segments 7n with the shaft L.

This arm W has'jaws l at its upper end, and

has a plate, Y, projecting from it. (Shown clearly in Fig. 4.)

The operation is as follows: By drawing the lever K outward,or in the direction indicated by arrow 3, the arm -W will be thrown back or outward from the plates H H, in 'consequence of the connection of the shafts L X by the geared segments k, and the toothed sector E will at the same time be drawn by the cor-d M in the direction of arrow 2, and the slide I moved forward between the plates H H by the cord J in the direction indicated by arrow 4,

the sector E, when the lever .K is drawn fully back, being held by the catch V, which hooks over a pin, a", on the s egment. As the arm W moves back, the' wire A", the end of which is held between thejaws l, is drawn back with it,

' and unwouud from the Spool P.

formed between the-spool P and pulley Q by the ratchetse, when the pulley slips, the arm 4W still moving, and when the plate Y comes in 'Contact with slide I, through the slot of which the wire passes, shovingr said slide backward between the plates H H, thel wire pessingjnto the notch c of the circular plete G, both parts of the wire being now in "c, and between theja-ws l, which come in contact with 'the catch V, and liberate the sector E, which is moved, under the action of spring I, in the direction indicated by arrow 1, the plate Q being thereby rotated through the medinm of pinion F, which gears into E, andthe wire being consequently twisted,and then cutot" by a cutter, Bx, above plate G.

The wire, previous to being cnt ofi', is caught' between lthe jaws i by n wedge-shaped pend-L ant, m, in the support n, which 'spreads the jaws to receive the wire.y e e Having thus described our invention, we claim as new and desire to secure by Letters Patentf* l. The toothed sector E, in connection with thepinion F, slotted plate G, the erm W,'cor rying the-wire A", and the knife or cutter Bf, all arranged to operate in the manner substantially as and for the purpose set forth. l

2. The arrangement ofthe spool P and pnl.- ley Q, with theratchets e e, in connection with 'the bend R and lever S, substantially as and -for the purpose specified.

3. The slotted slide'l, connected with the lever K, and arranged to operate in connection with the arm W, for the purpose set forth.

4. The nrran gement of the a-rmW on shaft X, in combination with the levers K and S, silbstantially as shown, so that they willl move simultaneously by the application of power to lever K, as and for the purpose as described.

5r. The spring-catch V and the spring T, a1'- 'ranged with the toothed sector E, in order to h old the same until the twist is to be given the band, and then to move the sector and give the twist, substantially as described.
